Review of Vivitar 4K Dual Screen Action Cam

Submitted by charm on Fri, 02/12/2021 - 10:07
The good, bad, and ugly side of the Vivitar 4K Dual Screen Action Cam as purchased at Walmart. The DVR922 was pretty cheap, I bought mine for $39.99 CDN (however I also spent this amount on a 128GB Micro SD/TF card, but more on this later). As an action camera it can take 4K video at 30 frames per second. The camera comes with more accessories than are marketed on the front of the case. Thankfully one of those accessories is a USB cable that can be used to connect the camera to the computer. Once connected the camera can be used as a USB drive, as a web cam (see details in bad section), or to charge the battery. The battery for the DVR922 is removable, but there's more bad news in the bad section. It's worth mentioning that I tested the DVR922 under Xubuntu Linux, so Vivitar gets points for not using some proprietary protocol to lock the camera to particular operating systems.

Xubuntu 20.04 Thunar archive bug

Submitted by charm on Mon, 02/08/2021 - 13:48
There is a bug in the archive plugin for the XFCE-based file manager Thunar in Xubuntu 20.04 and Linux Mint 20.1. The bug appears when you right click on any LibreOffice file. Normally you should be able to "create archive" when you click on a file in Thunar, this is the case for most files, but not LibreOffice files (.ods, .odt, etc.).

What's on my (physical) Linux bookshelf - 01/19/2021

My Linux bookshelf on January 19, 2021

Like so many people my collection of books has mostly gone digital. When we moved to our apartment 12 years ago we condensed two apartments into one. At the time I had about 10 small boxes of mostly tech-related books. Most apartments don't have the storage space a house does. Ours in particular has one small storage unit. Merging two families into one of the first things to go was my book collection. It was an easy choice to make in order to make space for more important family items (mostly Christmas decorations).

Piper, configure your Logitech G502 Hero mouse

Several months ago I bought a Logitech Hero 502 mouse on sale ($49.99CDN was $99.99) at Canada Computers. Recently I discovered Piper, a program that provides a graphical way to configure the Logitech Hero 502, and several other Logitech (and a few other brands of) mice. For a full list of Piper supported mice see the libratbag list of devices here: https://github.com/libratbag/libratbag/tree/master/data/devices. Piper is a graphical front end to libratbag.

Diablo III on Xubuntu 20.04 Linux brief overview

It works, not as good as it does on Windows 10, but it's very playable with some changes. I had to make some changes for to increase performance, but this might not be as much of a factor if you have a better video card.

[Advanced] Configuring LIRC 0.10x in Ubuntu 20.04

Submitted by charm on Mon, 11/23/2020 - 19:11

LIRC is a software package that lets you use common remote control with certain programs like KODI. Ubuntu 18.04 used to use LIRC version 0.9x. LIRC was recently upgraded and the new version is vastly different than the previous version. When LIRC was installed in earlier versions it specifically prompted the administrator to select which remote to use (usually something like Windows Media Centre Edition (MCE) remote). This doesn't happen with the new version, 0.10x, in Ubuntu 20.04. This problem seems to be one that a lot of people have. Here's what worked for me.

Automating a .deb Debian package for Fasteroids

Automating a .deb Debian package for Fasteroids

Many versions of Fasteroids ago I made a 3rd download available in the form of a .deb install-able Debian software package. To create the Debian package I followed a tutorial that involved copying a template and editing a number of files manually. Not only is this not the prescribed method for creating Debian packages, but it was a lot of manual work that left room for a lot of editing errors.

This is a list of 14 programs I use on my Xubuntu 20.04 Linux workstation. Most of the software isn't installed during the installation of Xubuntu, but I believe they're helpful programs for typical desktop users.
